terial on a continuous sheet. These short sections of perfect materialare rolled on a remnant roll, sometimes three or four pieces beingplaced on the same roll, depending upon the length of the individualpieces.

While inspecting sheet material in the past, it

has been found necessary to cut out the short pieces, roll themindividually, and stand them aside. When a sufiicient number of shortpieces were on hand, they were unrolled, reinspected and then rolled onremnant rolls. of pieces per roll varied, depending upon the size of thepieces. This was an extra operation in the inspection of sheet material.

In order to overcome the disadvantages out- 7 Claims. (01. 242-58) Thenumber lined above in the inspection, rolling, and packaging of sheetmaterial, the device illustrated and described herein was developed. I

An object of this invention is to provide an elevator for storing aremnant roll, the top of said elevator forming a portion of theinspection table surface during the normal use of the inspection table.

Another object of this invention is to' provide a storage spaceforremnant rolls inwhich the roll is convenient for use when necessarybut does not interfere with the workman.

A still further object of this invention is'to provide an arrangementwhereby short remnant pieces of sheet material are inspected whenencountered, rolled, wrapped, and labelled, thereby eliminating thenecessity for performing the subsequent operation of inspecting,wrapping, and labelling. I a

In order that my invention may be more readily understood, it will bedescribed in connection'with the attached drawing in which:

Figure 1 is a diagrammatic view of the roll-up end of a sheet materialinspection table with the remnant storage elevator in its down orinoperative position;

Figure 2 is a diagrammatic view similar to Fig ure 1 except that theelevator is in a partially raised position so that theremnant roll isaccessible for, adding an additionalpiece jofniaterial thereto Figure 3is a diagrammatic view similar to the other views showing the elevatorin its partially raised position, and the roll-up stand is in its raisedposition; and 1 Figure 4 is a diagrammatic view showing the elevator inits fully raised position with the rollup stand also in its raisedposition.

Referring to Figure '1 there is shown an inspection table 2 over whichthe sheet material 3, such as floor or wall covering of the linoleumtype, passes while it is being visually inspected for defects. Thenumeral 4 designates a roll of linoleum on a roll-up device 5 on whichthe material is rolled after it has been inspected. The bearing forsupporting the spindle 6 of the roll is shown The roll-up stand 5 is ona hydraulic lift I so that the finished roll of sheet material can belifted from the roll-up bearings 6' and removed from the roll-up device.This is accomplished by the platform 8 on the top of the hydraulic liftengaging the roll of sheet material and lifting it from the bearings.Figures 1- and 2 show the roll 4 in its position with respect to theplatform 8 when the roll is supported in the bearings.

When the spindle 6 passes through the center of the roll 4 supported inthe bearings of the rollup device, the roll is lower than the portion ofthe table between the roll-up device and the wrapping device 9. In orderthat the finished roll may be easily rolled by hand from the roll-updevice 5 to the wrapping station 9, the section of the table Iiidisposed immediately adjacent the roll-up device 5 is attached to theroll-up stand by means of a hinge-joint 8 so that, as the rollup deviceis raised and lowered, the end of the table It is raised and lowered,pivoting about a hinge-joint H on the other end of the table I0.

' Disposed between the roll-up device '5 and the wrapping device 9 is anelevator, l2, the top l3o'f which forms a portion of the table surfacebetween the roll-up device 5 and the wrapping device 9 when the elevatoris in its lowered position. Below the top surface l3 of the elevator l2there is provided a shelf I4. The top l3, shelf I4, and guide surface I5of the elevator define a chamber suitable for storing an auxiliary orremnant roll it of the sheet material on which the short remnant piecesare rolled. The elevator I2 may be hydraulically operated. However, itwill be understood that any other means may be used for operating theelevator.

In order that the roll of sheet material It may be convenientlytransferred from the elevator I2 110 the roll-up device 5, it is;-necessary that the elevator be capable of risingrashfgh as the roll- 3up device 5 when the same is in its upper position. This is necessarybecause, if the sheet material in the roll [6 is linoleum or the like,it is too heavy to roll up the inclined surface N by manual force. Toovercome this difiiculty the table portion I is mounted in slidebearings at the side adjacent the elevator. Attached to the bottom ofthe table by means of hinge-joints is a pair of rods or pins I! whichpass through the bearings 18 secured to the table support 19. Attachedto the bottom shelf [4 of the elevator I2 is a pair of hooks 20 whichengage the underneath portion of the table [0 and raise it with theelevator until the table portion in is level. When this conditionexists, the roll I6 is easily rolled by hand from the elevator l2 to theroll-up device 5. Figure 3 shows the roll-up device in its upperposition and the elevator l2 raised to the point that the hooks 25engage the under portion of the table II]. Figure 4 shows the elevatorl2 in its uppermost position with the portion level between the elevatorand the roll-up device 5.

The interior of the remnant roll housing of the elevator I2 is linedwith a sheet material lining 2| which is rounded to prevent the rollfrom be ing damaged by striking the sides of the housing.

In the operation of this device, when a short piece of perfect materialis encountered between defects in a continuous piece of sheet material,the 'short piece is rolled on a remnant roll. To accomplish thisoperation using the present invention, the roll-up; device 5 is elevatedto its top position for removal of the completed roll of material. Inorder to have access to the remnant roll, the elevator 12 is raised tothe position shown in Figure *4. The raising of the elevator l2 alsoraises the end of the table [0 which is engaged by hooks 20 which raisethe pins I! in the slide bearings 18. The remnant roll is rolled fromthe housing formed in the elevator over the table ID to the roll-updevice 5. The roll-up device is lowered so that the spindle in thecenter of the remnant roll rests in the bearings on the roll-up device5. After the remnant has been placed on the roll, the roll-up device isagain elevated to remove the spindle from the bearings. If it is desiredto return the remnant roll to the elevator, the roll is rolled acrossthe portion 10 into the housing and the elevator lowered. When theelevator is lowered, the end of the table II! drops again until itengages th support l9 at which point the dropping of the table stops andthe elevator continues its downward movement until the top of theelevator is even with the end of the portion I0. 1

If the remnant placed on the roll is the last remnant to be placed onthat particular roll, the elevator is lowered before the roll is removedfrom the roll-up device 5 and the roll is rolled from the roll-up device5-onto the wrapping device 9. This arrangement corresponds to that shownin Figure 3, except that the elevator is in-the down position.

It will beclear from this disclosure that I have developed a remnantelevator in which the remnant roll is kept convenient to the roll-updevice during the inspection and wrapping operation. However, theremnant roll is fully out of the way of the workman and, therefore, doesnot interfere in any way with the normal functioning. of. the inspectionoperation.
